Think we all used to do the night feed ,,and not feed if we were lamping,,but after seeing a good few dogs going over or to a standstill,,,you soon learn,,,..
Feed them at tea time,,out after midnight,,,and I've never seen any dog not perform properly,,by being fed befor hand,,,provided there's time to digest...

I bet the lads that feed last thing at night,,,befor they go to bed....wouldn't think
